[Solved]-highcharts, highstock without jQuery-Highcharts

i see three questions in your case:

1) to get object when creating chart, you have two ways:

• with jquery:

  var chart = $(element).highcharts('stockchart', options).highcharts();
  

• without jquery:

  var chart = new highcharts.stockchart(options);
  

2) error #17:

"the requested series type does not exist"

is caused by type : 'stockchart'. type is reserved for a series type. as @raeen hashemi said, to create highstock, use different constructor: new highcharts.stockchart(options).

3) yes, you can pass an object to renderto: http://jsfiddle.net/yvxwa6oq/

new highcharts.stockchart({
    chart: {
        renderto: document.getelementsbyclassname("container")[0] 
    },

    series: [{
        name: 'usd to eur',
        data: [10, 20]
    }]
});

4) this - honestly, i'm not sure why you need access to this somewhere else than event handlers. instead use highcharts.charts[index] or stored variables like chart or $(element).highcharts()
